Issue
When opening a website, a warning message appears stating that "Certificate verification problem detected" or that "Authenticity of the domain to which encrypted connection is established cannot be guaranteed".
Cause
The website may not be safe. There is a possibility that intruders may steal your account data and other personal information. We do not recommend visiting such websites.
For detailed information about what can cause the message to appear, see the section below.
If the warning appears not for websites but for applications installed on your computer, this means default encrypted connections scan settings have been changed. To fix the issue, restore the settings to default.
Solution
If you are sure that the website is safe (for example, if it's the official Microsoft website or an official page of your bank) and you visit it regularly, add this website to the exclusions. See the instructions for the following applications:
If the notification appears on a website you don't use often, you can allow opening it once. To do so:
- Click Show details → I wish to continue in the browser window.
- Click Continue in the pop-up window.
If you are not sure if the website is safe, you can check it with OpenTip before proceeding.
